Bitcoin Halving

How the Bitcoin Halving Affects the Price of Bitcoin

A light-bulb flashed over my head the first time I really understood the effects of the Bitcoin halving on the price of Bitcoin.

Knowing what the Bitcoin halving is, and how it affects the price is essential for anyone seeking to understand Bitcoin.

The short answer:

The Bitcoin halving causes a shift in the supply/demand balance, leading to an exponential rise in the price of Bitcoin. This happens every four years and is the backbone of the value of Bitcoin. In addition, it also sparks a hype cycle, pushing the price even higher, eventually leading to a price crash of 80%-90%.

In my opinion, it is the backbone of Bitcoins value and the main reason why more and more people, institutions, and governments keep throwing money at it.

Simply put, the Bitcoin halving is an event happening every four years that decreases the reward that miners receive for hashing blocks and validating transactions.

Why does cutting the miner rewards in half every four years make Bitcoin more valuable? Why should you care about this?

Because it creates scarcity, exponentially increasing the value of Bitcoin.

We’ll go over all the necessary aspects of Bitcoin mining and Bitcoin fundamentals to give you a complete understanding of the Bitcoin halving. If you’re familiar with what the halving is, skip this part.

We’ll look at:

  • Bitcoin Mining
  • Block Rewards
  • The Bitcoin Halvings Effect on Price in the past
  • The Stock to Flow model

Bitcoin Mining – How it is Affected by The Bitcoin Halving

Bitcoin mining consists mainly of two things; validating transactions and hashing blocks.

Validating Transaction

Whenever someone transacts BTC, information about that transaction is double checked by miners. The wallet address of the sender and receiver, the time and date, as well as the amount of BTC transacted.

The Bitcoin miners then decide if the transaction actually happened the way it was registered.

Then, Once the transaction is verified, it’s placed in a “block”. A block is basically a bunch of chunked up information about a few thousand transactions.

So, miners double-check all BTC transactions, and place information about them in blocks.

The next step is to add this block to “the chain”, which is the public database everyone can check out.

For a block (information about a few thousand transactions) to be added to the chain (the public database), it first needs to be “hashed”.

Hashing Blocks

This is essentially a guessing game with up to trillions of possible answers:

Bitcoin miners are trying to find the right “hash”, which is a string of numbers/characters unique to each block. The miner that finds the right answer receives a reward in the form of BTC, called the “block reward”.

The difficulty of Bitcoin mining, specifically the difficulty of the guessing game of hashing blocks, depends on the number of computers trying to guess it (total computing power of the network of miners).

If the number of miners go up, the difficulty goes up. If the number of miners go down, the difficulty goes down.

This is to ensure that each block takes approximately ten minutes to hash no matter how much CPU you put into it.

The chart below shows us the total computing power of the network measured in Terra Hashes/second. It’s safe to say that the 2017 bull run sparked a Bitcoin mining mania. (Source:

Bitcoin mining total hashrate

Now, where does the halving come in?

Remember, the halving is an event where the block rewards are cut in half. This means that hashing blocks produce half as much BTC as it used to.

That sounds like a bad thing, but it’s actually the backbone of Bitcoins value.

How The Bitcoin Halving Affects the Block Rewards

We established earlier that “block rewards” are the BTC that miners receive for hashing blocks.

Now, what the halving actually does is cutting the block rewards in half.

Also, we have Bitcoin halvings every four years or so.

This means that the profitability of mining Bitcoin is exponentially decreasing, at least in terms of BTC.

Why then, is the total computing power of Bitcoin miners exponentially increasing?

Why do more and more people mine Bitcoin, when the rewards are cut in half every four years?

The fact that the computing power of the Bitcoin network is only increasing tells us that miners have long-term faith in the price Bitcoin.

This is why:

Even though the BTC reward is cut in half every four years, it doesn’t mean that the USD value of the received block reward is decreasing.

In other words, miner believe that the price of Bitcoin will more than double every four years. If they didn’t, it would be absurd to invest millions of dollars into mining equipment.

The halving of block rewards itself pushes the price of Bitcoin up:

Think about it, the only way to produce new Bitcoin is through mining. This is the a big part of the selling pressure of the market.

Every four years Bitcoin miners create 50% less Bitcoin, effectively cutting the supply (selling pressure) from miners in half.

Given a constant demand, the price must increase, given the laws of economics.

In fact, the halving is what started the last two bull markets, pushing the Bitcoin price up several thousand percent.

Below you see a chart of the Bitcoin price together with vertical lines representing the previous Bitcoin halvings:

Bitcoin halving effect on price

As you can see, the price doesn’t react instantly to the halvings, but after some time, it starts increasing exponentially.

It has to increase due to a lack of supply, given the constant/increasing demand.

Let’s take a closer look at them, one by one:

First Bitcoin Halvings Affect on Price

The first Bitcoin halving took place in the end of November of 2012, cutting the block rewards from 50 BTC to 25 BTC.

This means that miners went from receiving 50 BTC per block hashed, to 25 BTC per block.

Let’s zoom in on the chart and look at what we can derive from it:

First Bitcoin halving effect on price

I’ve meassured the price inrcrease from the halving to the peak, as well as how long it took to get there. As you can see, Bitcoin gained 10 000% over 52 weeks. It went from a price of 11.5$ to 1148$ – approximately 100x in one year.

Second Bitcoin Halvings Affetc on Price

The second Bitcoin halving took place in the in July of 2016, cutting the block rewards from 25 BTC to 12.5 BTC.

Let’s zoom in on the chart and look at what we can derive from it:

Second Bitcoin halving effect on price

The effects of the bitcoin halving was a price increase of 3000%, giving us 1/3 of the gains we got from the first halving. The time it took reach the peak also increased, from 52 to 74 weeks – 22 weeks longer.

This indicates that the gains we receive are lower, and slower.

The gains seems to be cut in thirds for each halving, as well as take 5-6 months longer to reach the peak. This is highly speculative to suggest, and is by no means “a fact”.

Third Bitcoin Halvings Affetcs on Price

The third Bitcoin halving took place in May of 2020, cutting the block rewards from 12.5 BTC to 6.25 BTC.

Let’s zoom in on the chart and look at what we can derive from it:

Third bitcoin halving effect on price

I’ve theorized on what could happen if the gains really do decrease with 2/3 and take 22 weeks longer for each halving, and reached a conclusion:

The two previous halvings indicates that we will reach a Bitcoin price right around 100 000$ in 2022 approximately 10x in 2 years.

As you can see above, the price has reacted to the halving, strengthening my belief that the halving, by necessity, increases the price of Bitcoin.

A guy who goes under the name “PlanB” tried to predict the price of Bitcoin after each halving, creating the legendary “Stock to Flow model”.

I’ll break down what “the stock to flow” means, and show you the model:

The Stock to Flow of Bitcoin

The stock to flow of an asset tells us something about how much is produced vs. how much there already is of the given asset.

Specifically, it tells us how many years it would take to double the supply of the given asset, at the current rate of production.

In Bitcoins case, this means that a stock to flow of 10, would mean that miners need 10 years, at the current mining rate, to double the amount of Bitcoin in circulation.

In other words, it’s a number that tells us how much Bitcoin is being mined relative to how much Bitcoin there already is.

A high stock to flow is good for price and stability, and is often read as a sign of scarcity.

Currently, the Stock to flow is 54.

This means that at the current speed of mining new BTC, miners need 54 years to double the supply of Bitcoin.

Now, this is why the halving is so fundamental to Bitcoins value:

The halving cuts block rewards in half, and therefore the production rate of Bitcoin in half, every four years.

This doubles the stock to flow every four years!

Stock to Flow and Price

When looking at precious metals, a higher stock to flow usually means a higher price.

Gold is the metal with the highest stock to flow, which is the biggest reason it’s highly valued and acknowledged as a superb store of value.

Now think about this:

After the next halving, Bitcoin will have a higher stock to flow than gold!

Below you see the model created by PlanB, modeling the price of Bitcoin by the stock to flow. (Source:

Bitcoin Stock to flow
The colorful dots are the price of Bitcoin. The line is the predicted price based on the stock to flow. The color of the dots tell us how many days the next halving is into the future (right vertical axis). You see the price in USD on the left vertical axis, and the time measured in years on the bottom horizontal axis.

This model can be overwhelming, but stay with me.

Let’s go through it, and see what we can learn about the bitcoin stock to flow and it’s relationship with the price:

Bitcoin Halving Effects on Price – Stock to Flow

We can clearly see that the Bitcoin price has gone above the predicted price after both halving we’ve had in the past. Remember, we had our first halving in the end of 2012, the second in the middle of 2016, and our last one in May of 2020.

The Stock to Flow model predicts that Bitcoin will, in this cycle, reach 100 000 USD. This strengthens the prediction we made looking at the ROI from the previous halvings in the parts above.

We also see that we tend to overshoot the target, and go far beyond the predicted price. This lead me to think that a price prediction of $100K is on the conservative side. $150K – $200K might be more realistic.

Effects of Bitcoin Halving – Conclusion

Again, the halving is the event happening every four years where the block reward miners receive for hashing blocks are cut in half.

This reduces the supply of Bitcoin, and doubles the stock to flow.

After the next halving, the stock to flow of bitcoin will be greater than that of Gold.

PlanB has created a model predicting the price of Bitcoin at the different stock to flow levels. It has proven to be accurate until now, and personally, I believe it will continue to predict the Bitcoin price with high accuracy.

We’ve seen how the historical effects of the Bitcoin halving have acted as a catalyst for the previous bull markets, and it seems like history is repeating it self.

The Stock to flow model is indicating a six figure Bitcoin, which is in line with most other models trying to predict the price of Bitcoin.

I’ve created a guide on how to increase ROI (Return on investment). This metric is the most important factor when it comes to investing.

When investing in traditional markets like stocks and bonds, there’s not too much you can do to significantly increase your ROI.

This is not the case in crypto markets.

There ARE ways you can significantly increase ROI. I’ve created a free guide on 4 easy ways to increase ROI.

I do all four of them my self, and know for a fact that they can increase ROI by up to hundreds of percent.
